What could cause Canker sores?

The exact cause of canker sores is not fully understood, but several factors are believed to contribute to their development. Possible causes include minor injuries to the mouth from dental work, aggressive brushing, or accidental biting, as well as food sensitivities or allergies to certain acidic or spicy foods. Additionally, canker sores may be linked to underlying health conditions such as weakened immune system, nutritional deficiencies, or hormonal changes. Emotional stress and hormonal fluctuations are also thought to play a role in triggering canker sores in some individuals.

Maintaining good oral hygiene, such as regular brushing and flossing, can help prevent canker sores. It is also important to avoid foods that may trigger or worsen canker sores, such as acidic fruits, spicy foods, and foods with sharp edges that can injure the mouth. Additionally, managing stress and seeking treatment for any underlying health conditions can also reduce the likelihood of developing canker sores.
